INSTRUMENT-HOLDER FOR DENTISTS.

SPECIFICATION forming part of Letters Patent No. 774,879, dated November15, 1904.

Application filed September 5,1902. Serial No. 122,165. (No model.)

To all whom it may concern: 7

Be it known that I, WILLIAM G. HULLHORST, a citizen of the UnitedStates, residing at T0- ledo, in the county of Lucas and State of Ohio,have invented certain new and useful Improvements in Instrument-Holdersfor Dentists; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same, referencebeing had to the ac companying drawings, and to the figures of referencemarked thereon, which form a part of this specification.

In the practice of their profession dentists have difficulty inarranging and disposing of their instruments in such a manner that theyare easy of access, readily found, and when not in use secured againstdust and handling.

My invention rel-ates to means for overcoming these difliculties; and itis designed to furnish an instrument-holder in which all of theinstruments may be brought within convenient reach of the operator andexposed to plain view, so that the proper instruments may be selectedwithout delay. I attain these objects by means of devices andarrangement of parts hereinafter described,'and shown and illustrated inthe accompanying drawings, in which Figure 1 is a perspective, view ofmy device in position to be returned to its cabinet, and in which Fig. 2is a like view of my device ready for use. 7

Like numerals of reference indicate like parts in both views.

In the drawings, 1 is a cabinet having a drawer-compartment 2 in whichslides in and out a drawer 3. The sides of the drawer have forwardextensions 4, which at front and top are chamfered downwardly, as at 5.Between the two side extensions 4 fits loosely a block 6, which ispivoted, as at 7, between the two side extensions. The front 8 of theswinging block corresponds in height and width with the opening of thecompartment 2 and is finished to correspond with the finish of thecabinet. On its upper face the block 6 is provided with a number ofholes bored into the block a sufficient depth to receive the shank ofthe instrument, of which one is shown in place, as at 9. The front partof the block, which is thicker vertically than the remainder of theblock, is stepped downwardly, as shown, and these steps are providedwith holes to receive the shorter instruments. From the inner side ofone of the side extensions projects a pin 10, which forms a stop tolimit the upward movement of the back part of the block on its pivot.The downward movement of the block is limited by its contact with thefront piece 11 of the drawer.

The operation of my device'is as follows: The front of the block 6 ispulled out toward the operator the required distance by means of a knobor suitable handle and is tilted downwardly, as shown in Fig. 2, so thatthe rear of the block comes in contact with the stop'lO. The block isnow in such position that the operator can look directly down upon theexposed ends of all of the instruments, each one of which is in itsproper place. The angle of the block to the horizontal will nowcorrespond with the bevel of the front ends of the side extensions,sothat the sides do not cast any shadows upon the block or interferewith the quick selection and removal of the proper instruments. When notin use,

the front end of the block is swung upwardly upon its pivot into thesame horizontalplane with the drawer, and the drawer and block arepushed horizontally back into the drawercompartment and-there properlysecured.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s.
